What would you do with an elephant tusk?

DH has a 7 inch ivory elephant tusk tip, it was originally mounted on a metal stand and intended as an ornament (nice).

He aquired it from his grandparents who lived in Africa in the 1920s, so it is from an elephant that died many decades ago, but all I can think of is the collapsed carcass of the elephant that was killed for it's ivory. I want it out of the house.

Just throwing it away seems disrespectful to the elephant somehow..

Obviously I don't want to sell it, even if it were legal, I don't want money from it.

Have considered giving it a burial (sounds loony, I know), but wondered if any conservation or educational organisation could use it?

I'll have to disagree there Soup, it is said to be more likely to led to an increase in new ivory made to look like old ivory. The idea is to stop all trading in exotic animal parts, new or old, to reduce desirability and keep the stigma current.

"If you obtained the specimen a long while ago, or you have inherited it, you may not be able to prove the date you acquired it. Please contact us, as we may be able to suggest ways in which its acquisition date can be determined. For example, it is possible for experts to give an approximate date which will be good enough for us to be able to determine if it pre-dates its listing on CITES, or whether it meets the antiques derogation."

This would clear up whether you could legally sell it (sounds as if you should be able to). I'd sell and donate. Otherwise, burial or cremation?
